Circuit Board Design for Antennas
Differing from common PCB board designs, antennas bring a unique set of considerations to PCB design. The wireless PCB assembly process begins with drawing a schematic diagram of the PCB. Here we’ve highlighted the essential 5 PCB board design guidelines.

Determine Your PCB Board Design Rules Before Layout
To maximumly avoid the most errors that will lead to components shifting and re-routing later, when starting a new printed circuit board design, you should first take into account several basic factors:
- Antenna Information: frequency range, dimensions, expected gains, efficiencies, etc. Mastering these will directly determine the size and shape of your PCB, and the necessary electronic components.
- Crucial factors such as clearance area and the ground plane size are also what you need to make clear at the beginning.
- Talk to your PCB design rules fabrication house to confirm if they stress special requirements. These prepared processes will greatly benefit your ongoing next step.
Fine-Tuning Your PCB Layout and Routing
The placement process starts after setting the board design rules, you can strategically consider the prime space available on your board. Place components on the PCB appropriately by avoiding crossing high-frequency signal lines with sensitive signal lines to ensure that sensitive components are separated from the signal.
Once the components’ placements are done, it’s now time to route power, ground, and signal traces to ensure signals have a clean and trouble-free path of travel.
- Defining the trace width, spacing, etc., and keeping them meets the manufacturing specifications.
- High-frequency signal lines should be kept as short as possible and avoid sharp bends.
Do not omit the consideration of the impedance matching of the feed line to the antenna.
Another key factor is the ground plane space, which is a matter for good performance of embedded antennas. The more miniaturized the device, the more paramount it is to have ample space. For example, at frequencies below 1GHz, it is better to keep at least 90-100mm of ground plane antennas for effective working in these devices.
Soldering with Care
To achieve a successful PCB assembly, soldering is an important step in wireless PCB assembly. This step requires extra attention and care.
- Don’t place vital components beside the board’s heating part.
- Overheating can damage the circuit board and other components. To ensure the soldering temperature can be maintained, you should pay attention to the thermal relief solutions on the PCB. The idea behind thermal relief is straightforward: it slows the rate at which heat is dissipated into the plane during soldering, which helps prevent cold joints.
Optimizing, Testing, and Validation.
Two golden times may give you a big shot at your improvement. One is after the completion of your design with the design tool. Using simulation tools to test the performance of your circuits, and checking aspects like signal integrity and power integrity will correct your board wireless system.
The other is during the prototyping. Now you can move on to prototyping after your assembly is perfectly finished. Prototyping testing again and again is a must to evaluate whether the antenna performs well on the circuit board.
In short, the final guidance for PCB integration is to make sure the printed circuit board passes quality control. Make sure to integrate the right inspection and testing methods. After that, your wireless circuit board is ready to perform at its best.
